Regarding YUV422 video encode using VPU

shilpac — Fri, 20 Jun 2014 10:56:09 GMT

Hi,

I am trying to receive YUV422 format video data using videotestsrc and encode using vpuenc element of gstreamer 0.10. But when I do so ending up in an error.

When I saw capabilities of vpuenc gstreamer element using "gst-inspect-0.10 vpuenc", support for YUV422 is not found.

While running through gst-fsl-plugins code I observed the availability of two vpu elements "vpuenc" and "mfw_vpuencoder". Looks like mfw_vpuencoder has support for YUV422. But the gst-fsl-plugins rmp installed isn't providing mfw_vpuencoder element on IMX6Q though libraries related to them are available.

Set up details

Hardware: IMX6Q Sabrelite Eval Board

Release: Yocto 1.4

Build: Linux 3.0.35_1.1.0

Media Framework: GStreamer0.10

Need your inputs.

Thanks,

Shilpa Chandrappa

in fact, mx6 IPU can change yuv422 to yuv420, you don't install mfw_vpuencoder to support yuv422,

Dear Guanqiong,

How can I change the pixel format from YUV422 to YUV420 by using mfw_vpuencoder?

And I heard the pixel format will be converted from YUV422 to YUV420 by configuring the CPMEM's PFS, UBO and VBO in IDMAC as another method.

Could you tell me the method if you konw?

Best Regards,
